IMPROVEMENTA'IN GAG E-CCCKS.

Specification forming part of Lettere Patent No. 141,4l6, dated August 5, 1873; application filed February 3, 1873.

To ail whom it may concern:

Be it known that I, HARRY J. BAILEY, of Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Gage-(Jocks 5 and. I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawing making a part of this specification, in which- Figure 1 is a side elevation of my improved gage-cock. Fig. 2 is a longitudinal vertical section thereof, land Fig. 3, by a sectional view, illustrates a modification thereof.

Like letters of reference indicate like parts in each.

My improvement consists in the arrangement of a cam or eccentric, having on its periphery a soft-metal seat, with its face operating directly against the outer open end of the barrel or bore of a gage-cock, in connection with a weighted handle; also, in the combination of a cam or eccentric, a spindle for opening and closing the bore, and, affixed thereto and moved thereby, a twisted cleaner, which moves in and lengthwise of the bore; and, also, in the combination of the cam or eccentric with its bearings and seats, the spindie, the cleaner, and weighted handle.

To enable others skilled in the art to make and use my improvement, I will proceed to describe its construction and inode of operation.

The body B has the usual threaded end b, and the ordinary barrel a. The outer end of the barrel is properly formed to be closed by the end of the spindle D, which abuts thereon, proper packing being introduced, if desired, in order to secure a tight joint. Back of the seat thus formed the spindle D is slotted vertically through, so as to receive a cam or eccentric, It, the full sides of the periphery of which are made to bear against the spindle in front and rear, so as to be operative in forcing the valve-end of the spindle to its seat on the port-end of the barrel a, or by a reverse movement draw it from its seat. The rear end of the body B is bifurcated vertically, and the upper edges of the bifurcations d are cut down to proper shape,

eccentric R. The stem r of the eccentric is` connected to a weighted handle, g, which acts to keep the eccentric in position for closing lthe cock. A

In order to keep the barrel ct from lling up with sediment, or if it becomes clogged to clean it out, I attach to the valve-end of the spindle D a twisted metallic strap, e, which projects along into the barrel ci. Then with every movement of the spindle D the cleaner' e acts to prevent the deposit of sediment, and keeps the barrel always open. But instead of being a twisted strap, the cleaner may be a straight rod or wire, with danges or wings projecting outwardly therefrom at any desired angle, so that when such cleaner is moved longitudinally it will act to stir up or scrape out the sedimentary matter, 1f any, in the barrel a. These devices are made as shown partly to enable them to be removed v with facility whenever desired.

rIhe eccentric R may be lifted vertically off its bearings, and' taken out of the slot in tn e spindle D, in which it works. The spindle is then free to come out endwise, and the cleaner e, in coming out, will scrape ont any sediment which may have collected in the barrel a.

.As embodying a part of my improvement in a modified form, I have shown in Fig. 3 the eccentric R hung in' the bifurcated outer end of the body B, and with the full side of its periphery bearing against the end of the barrel d, and capable 0f being rotated, so asl to open the end of the barrel. In this use of the eccentric, it should have a working face of soft metal or other suitable material, such as will, by pressure or the guiding motion required, automatically form a seat suitable for closing the end of the barrel a. The handle in this case, as also in Figs. l and 2, should generally be weighted. Both theY eccentrics described are hung, as shown, with their centers of motion so near the axial line of the barrel a, that when brought to position for closing the cock, the steam pressure, acting nearly or quite in their radial line, cannot force them from their seats, even if weighted handles were not used. The eccentric so lllltl moved thereby, the cleaner e, arranged and operated substantially as set forth.

3. The combination of the cam or eccentric R, bearings 1", seats d, spindle D, cleaner c, and. Weighted handle, substantially as set forth.

In testimony whereof I, the said HARRY J. BAILEY, have hereunto set my hand.

HARRY J. BAILEY.
